Levitra discount prices

Until Ayushman Bharat, Indiaâs biggest experiment with public health insurance was the Rashtriya Swasthya Bima Yojana (RSBY), literally translated from Hindi levitra discount prices as âNational Health Insurance http://scoalaromaneasca.ca/where-can-i-buy-levitra/ Programâ. Until its levitra discount prices launch in 2008, nothing of this magnitude had been attempted. Ayushman Bharat is widely considered a large-scale upgrade of RSBY. The Government of India, on its levitra discount prices official website, india.gov.in, the National Portal of India, has had the humility to publicly admit to the failure of past efforts at public health insurance.

It goes on to position the RSBY as an attempt at succour. The target beneficiaries levitra discount prices of RSBY were families below poverty line (BPL). Depending on which estimate one looks at, the proportion of the population that is BPL varies from 20% to 30%. Even taking into account the lower end of the estimate, that is, 20%, the approximate population in 2017 that would fall in levitra discount prices the BPL category, out of a total population of approximately 1340âmillion, would be 270âmillion.

The number of families, assuming 4.9 persons per family, would be 55.1âmillion. Contrast this with the 35.8âmillion families enrolled under RSBY until 30 September 2017, the last date for which official government data are available, which is more than 9 years after its launch, there is a levitra discount prices shortfall of 35%. If we took the higher end of the estimate, that is, 30%, the approximate population in 2017 that would fall in the BPL category, out of a total population of approximately 1340âmillion, would be 400âmillion. The number of families, assuming 4.9 persons levitra discount prices per family, would be 81.6âmillion.

The shortfall would then be as high as 56%. One reason for this is that as of 30 September 2017, nine states/union territories of India (Chandigarh, Haryana, Jharkhand, Madhya Pradesh, Pondicherry, Punjab, Rajasthan, Uttar Pradesh and levitra discount prices Uttarakhand) were not part of the RSBY, as they â¦Adipose tissue inflammation has been proposed as a critical link between obesity and metabolic diseases, such as type 2 diabetes and cardiovascular diseases. In obese adipose tissue, macrophages and other immune cells are accumulated, triggering chronic inflammation. Elevated proinflammatory immune cells not only dysregulate adipose tissue function but also subsequently levitra discount prices elicit systemic inflammation through the production of inflammatory mediators.

Particularly, inflammatory cytokines from adipose tissue have been implicated in the pathogenesis of metabolic disorder, including insulin resistance in peripheral tissues.1 As the correlation between adipose tissue inflammation and metabolic diseases has been well established, the resolution of adipose tissue inflammation using anti-inflammatory agents, including nonsteroidal anti-inflammatory drugs, has gained the attention as one of the therapeutic potentials for prevention and treatment of obesity-induced metabolic diseases.2 In addition, evidence of the relationship between inflammation and hypoxia in obese adipose tissue has highlighted hypoxia-inducible factors (HIFs) as a novel target against adipose tissue inflammation.In obesity, pathological expansion of adipose tissue leads to local hypoxia through several factors, such as adipocyte enlargement, insufficient neovascularisation, decreased blood flow and increased uncoupling respiration.3 Adipose tissue hypoxia could stabilise and activate HIFs that are the key transcription factors to mediate hypoxic responses, such as angiogenesis, vasodilation, erythropoiesis and glycolysis. HIFs are heterodimers composed of oxygen-sensitive Î± subunit (HIF-Î±) levitra discount prices and constitutively expressed Î² subunit (HIF-1Î²). Duplication of ancestral HIF-Î± coincided with the evolution of vertebrates, and three Î± subunits â¦.

The National Commission for Allied and Healthcare Professions Act, 2020 and its implication for mental health. Indian J Psychiatry 2021;63:119-20The National Commission for Allied and Healthcare Professions Act, 2020 has been notified on March 28, 2021, by the Gazette of India published by the Ministry of Law levitra standard dosage and Justice. This bill aims to âprovide for regulation and maintenance of standards of education and services by allied and healthcare professionals, assessment of institutions, maintenance of a Central Register and State Register and creation of a system to improve access, research and development and adoption of latest scientific advancement and for matters connected therewith or incidental thereto.â[1]This act has created a category of Health Care Professionals which is defined as.

Âhealthcare professionalâ includes a scientist, therapist, or other professional who studies, advises, researches, supervises or provides preventive, curative, rehabilitative, therapeutic or promotional health services and who has obtained any qualification of degree under this Act, the duration of which shall not be <3600 h spread over a period of 3 years to 6 years divided into specific semesters.[1]According to the act, âAllied health professionalâ includes an associate, technician, or technologist who is trained to levitra standard dosage perform any technical and practical task to support diagnosis and treatment of illness, disease, injury or impairment, and to support implementation of any healthcare treatment and referral plan recommended by a medical, nursing, or any other healthcare professional, and who has obtained any qualification of diploma or degree under this Act, the duration of which shall not be less than 2000 h spread over a period of 2 years to 4 years divided into specific semesters.â[1]It is noticeable that while the term âHealth Care Professionalsâ does not include doctors who are registered under National Medical Council, Mental Health Care Act (MHCA), 2017 includes psychiatrists under the ambit of Mental Health Care Professionals.[2] This discrepancy needs to be corrected - psychiasts, being another group of medical specialists, should be kept out of the broad umbrella of âMental Healthcare Professionals.âThe category of Behavioural Health Sciences Professional has been included and defined as âa person who undertakes scientific study of the emotions, behaviours and biology relating to a person's mental well-being, their ability to function in everyday life and their concept of self. ÂBehavioural healthâ is the preferred term to âmental healthâ and includes professionals such as counselors, analysts, psychologists, educators and support workers, who provide counseling, therapy, and mediation services to individuals, families, groups, and communities in response to social and personal difficulties.â[1]This is a welcome step to the extent that it creates a diverse category of trained workforce in the field of Mental Health (Behavioural Health Science Professionals) and tries to regulate their training although it mainly aims to promote mental wellbeing. However there levitra standard dosage is a huge lacuna in the term of âMental Illnessâ as defined by MHCA, 2017. Only severe disorders are included as per definition and there is no clarity regarding inclusion of other psychiatric disorders, namely âcommon mental disordersâ such as anxiety and depression.

This leaves a strong possibility of levitra standard dosage concept of âpsychiatric illnessesâ being limited to only âsevere psychiatric disordersâ (major psychoses) thus perpetuating the stigma and alienation associated with psychiatric patients for centuries. Psychiatrists being restricted to treating severe mental disorders as per MHCA, 2017, there is a strong possibility that the care of common mental disorders may gradually pass on under the care of âbehavioural health professionalsâ as per the new act!. There is need to look into levitra standard dosage this aspect by the leadership in psychiatry, both organizational and academic psychiatry, and reduce the contradictions between the MHCA, 2017 and this nascent act. All disorders classified in ICD 10 and DSM 5 should be classified as âPsychiatric Disordersâ or âMental Illness.â This will not only help in fighting the stigma associated with psychiatric illnesses but also promote the integration of psychiatry with other specialties.

Available from. Https://www.indianjpsychiatry.org/text.asp?. 2021/63/2/121/313716 Introduction Thiamine is a water-soluble vitamin (B1) that plays a key role in the activity of several enzymes associated with energy metabolism. Thiamine pyrophosphate (or diphosphate) is the active form that acts as a cofactor for enzymes.

The daily dietary requirement of thiamine in adults is 1â2 mg and is dependent on carbohydrate intake.[1],[2] The requirement increases if basal metabolic rate is higher, for example, during alcohol withdrawal state. Dietary sources include pork (being the major source), meat, legume, vegetables, and enriched foods. The body can store between 30 and 50 mg of thiamine and is likely to get depleted within 4â6 weeks if the diet is deficient.[2] In those with alcohol-related liver damage, the ability to store thiamine is gradually reduced.[1],[2]Lower thiamine levels are found in 30%â80% of chronic alcohol users.[3] Thiamine deficiency occurs due to poor intake of vitamin-rich foods, impaired intestinal absorption, decreased storage capacity of liver, damage to the renal epithelial cells due to alcohol, leading to increased loss from the kidneys, and excessive loss associated with medical conditions.[2],[3] Furthermore, alcohol decreases the absorption of colonic bacterial thiamine, reduces the enzymatic activity of thiamine pyrophosphokinase, and thereby, reducing the amount of available thiamine pyrophosphate.[4] Since facilitated diffusion of thiamine into cells is dependent on a concentration gradient, reduced thiamine pyrophosphokinase activity further reduces thiamine uptake into cells.[4] Impaired utilization of thiamine is seen in certain conditions (e.g., hypomagnesemia) which are common in alcohol use disorder.[2],[3],[4] This narrative review discusses the neuropsychiatric syndromes associated with thiamine deficiency in the context of alcohol use disorder, and the treatment regimens advocated for these conditions. A PubMed search supplemented with manual search was used to identify neuropsychiatric syndromes related to thiamine deficiency in alcohol use disorder patients.

Neuropsychiatric Syndromes Associated With Thiamine Deficiency WernickeâKorsakoff syndromeWernicke encephalopathy is associated with chronic alcohol use, and if not identified and treated early, could lead to permanent brain damage characterized by an amnestic syndrome known as Korsakoff syndrome. Inappropriate treatment of Wernicke encephalopathy with lower doses of thiamine can lead to high mortality rates (~20%) and Korsakoff syndrome in ~ 80% of patients (ranges from 56% to 84%).[5],[6] The classic triad of Wernicke includes oculomotor abnormalities, cerebellar dysfunction, and confusion. Wernicke lesions are found in 12.5% of brain samples of patients with alcohol dependence.[7] However, only 20%â30% of them had a clinical diagnosis of Wernicke encephalopathy antemortem. It has been found that many patients develop WernickeâKorsakoff syndrome (WKS) following repeated subclinical episodes of thiamine deficiency.[7] In an autopsy report of 97 chronic alcohol users, only16% had all the three âclassical signs,â 29% had two signs, 37% presented with one sign, and 19% had none.[8] Mental status changes are the most prevalent sign (seen in 82% of the cases), followed by eye signs (in 29%) and ataxia (23%).[8] WKS should be suspected in persons with a history of alcohol use and presenting with signs of ophthalmoplegia, ataxia, acute confusion, memory disturbance, unexplained hypotension, hypothermia, coma, or unconsciousness.[9] Operational criteria for the diagnosis of Wernicke encephalopathy have been proposed by Caine et al.[10] that requires two out of four features, i.e., (a) dietary deficiency (signs such as cheilitis, glossitis, and bleeding gums), (b) oculomotor abnormalities (nystagmus, opthalmoplegia, and diplopia), (c) cerebellar dysfunction (gait ataxia, nystagmus), and (d) either altered mental state (confusion) or mild memory impairment.As it is very difficult to clinically distinguish Wernicke encephalopathy from other associated conditions such as delirium tremens, hepatic encephalopathy, or head injury, it is prudent to have a lower threshold to diagnose this if any of the clinical signs is seen.

Magnetic resonance imaging (MRI) brain scan during Wernicke encephalopathy shows mammillary body atrophy and enlarged third ventricle, lesions in the medial portions of thalami and mid brain and can be used to aid diagnosis.[11],[12] However, most clinical situations warrant treatment without waiting for neuroimaging report. The treatment suggestions in the guidelines vary widely. Furthermore, hardly any evidence-based recommendations exist on a more general use of thiamine as a preventative intervention in individuals with alcohol use disorder.[13] There are very few studies that have evaluated the dose and duration of thiamine for WKS, but higher doses may result in a greater response.[6],[14] With thiamine administration rapid improvement is seen in eye movement abnormalities (improve within days or weeks) and ataxia (may take months to recover), but the effects on memory, in particular, are unclear.[4],[14] Severe memory impairment is the core feature of Korsakoff syndrome. Initial stages of the disease can present with confabulation, executive dysfunction, flattened affect, apathy, and poor insight.[15] Both the episodic and semantic memory are affected, whereas, procedural memory remains intact.[15]Thomson et al.[6] suggested the following should be treated with thiamine as they are at high risk for developing WKS.

(1) all patients with any evidence of chronic alcohol misuse and any of the following. Acute confusion, decreased conscious level, ataxia, ophthalmoplegia, memory disturbance, and hypothermia with hypotension. (2) patients with delirium tremens may often also have Wernicke encephalopathy, therefore, all of these patients should be presumed to have Wernicke encephalopathy and treated, preferably as inpatients. And (3) all hypoglycemic patients (who are treated with intravenous glucose) with evidence of chronic alcohol ingestion must be given intravenous thiamine immediately because of the risk of acutely precipitating Wernicke encephalopathy.Alcoholic cerebellar syndromeChronic alcohol use is associated with the degeneration of anterior superior vermis, leading to a clinical syndrome characterized by the subacute or chronic onset of gait ataxia and incoordination in legs, with relative sparing of upper limbs, speech, and oculomotor movements.[16] In severe cases, truncal ataxia, mild dysarthria, and incoordination of the upper limb is also found along with gait ataxia.

Thiamine deficiency is considered to be the etiological factor,[17],[18] although direct toxic effects of alcohol may also contribute to this syndrome. One-third of patients with chronic use of alcohol have evidence of alcoholic cerebellar degeneration. However, population-based studies estimate prevalence to be 14.6%.[19] The effect of alcohol on the cerebellum is graded with the most severe deficits occurring in alcohol users with the longest duration and highest severity of use. The diagnosis of cerebellar degeneration is largely clinical.

MRI can be used to evaluate for vermian atrophy but is unnecessary.[20] Anterior portions of vermis are affected early, with involvement of posterior vermis and adjacent lateral hemispheres occurring late in the course could be used to differentiate alcoholic cerebellar degeneration from other conditions that cause more diffuse involvement.[21] The severity of cerebellar syndrome is more in the presence of WKS, thus could be related to thiamine deficiency.[22],[23] Therefore, this has been considered as a cerebellar presentation of WKS and should be treated in a similar way.[16] There are anecdotal evidence to suggest improvement in cerebellar syndrome with high-dose thiamine.[24]Alcoholic peripheral neuropathyPeripheral neuropathy is common in alcohol use disorder and is seen in 44% of the users.[25] It has been associated predominantly with thiamine deficiency. However, deficiency of other B vitamins (pyridoxine and cobalamin) and direct toxic effect of alcohol is also implicated.[26] Clinically, onset of symptoms is gradual with the involvement of both sensory and motor fibers and occasionally autonomic fibers. Neuropathy can affect both small and large peripheral nerve fibers, leading to different clinical manifestations. Thiamine deficiency-related neuropathy affects larger fiber types, which results in motor deficits and sensory ataxia.

On examination, large fiber involvement is manifested by distal limb muscle weakness and loss of proprioception and vibratory sensation. Together, these can contribute to the gait unsteadiness seen in chronic alcohol users by creating a superimposed steppage gait and reduced proprioceptive input back to the movement control loops in the central nervous system. The most common presentations include painful sensations in both lower limbs, sometimes with burning sensation or numbness, which are early symptoms. Typically, there is a loss of vibration sensation in distal lower limbs.

Later symptoms include loss of proprioception, gait disturbance, and loss of reflexes. Most advanced findings include weakness and muscle atrophy.[20] Progression is very gradual over months and involvement of upper limbs may occur late in the course. Diagnosis begins with laboratory evaluation to exclude other causes of distal, sensorimotor neuropathy including hemoglobin A1c, liver function tests, and complete blood count to evaluate for red blood cell macrocytosis. Cerebrospinal fluid studies may show increased protein levels but should otherwise be normal in cases of alcohol neuropathy and are not recommended in routine evaluation.

Electromyography and nerve conduction studies can be used to distinguish whether the neuropathy is axonal or demyelinating and whether it is motor, sensory, or mixed type. Alcoholic neuropathy shows reduced distal, sensory amplitudes, and to a lesser extent, reduced motor amplitudes on nerve conduction studies.[20] Abstinence and vitamin supplementation including thiamine are the treatments advocated for this condition.[25] In mild-to-moderate cases, near-complete improvement can be achieved.[20] Randomized controlled trials have showed a significant improvement in alcoholic polyneuropathy with thiamine treatment.[27],[28]MarchiafavaâBignami syndromeThis is a rare but fatal condition seen in chronic alcohol users that is characterized by progressive demyelination and necrosis of the corpus callosum. The association of this syndrome with thiamine deficiency is not very clear, and direct toxic effects of alcohol are also suggested.[29] The clinical syndrome is variable and presentation can be acute, subacute, or chronic. In acute forms, it is predominantly characterized by the altered mental state such as delirium, stupor, or coma.[30] Other clinical features in neuroimaging confirmed MarchiafavaâBignami syndrome (MBS) cases include impaired gait, dysarthria, mutism, signs of split-brain syndrome, pyramidal tract signs, primitive reflexes, rigidity, incontinence, gaze palsy, diplopia, and sensory symptoms.[30] Neuropsychiatric manifestations are common and include psychotic symptoms, depression, apathy, aggressive behavior, and sometimes dementia.[29] MRI scan shows lesions of the corpus callosum, particularly splenium.

Treatment for this condition is mostly supportive and use of nutritional supplements and steroids. However, there are several reports of improvement of this syndrome with thiamine at variable doses including reports of beneficial effects with high-dose strategy.[29],[30],[31] Early initiation of thiamine, preferably within 2 weeks of the onset of symptoms is associated with a better outcome. Therefore, high-dose thiamine should be administered to all suspected cases of MBS. Laboratory Diagnosis of Thiamine Deficiency Estimation of thiamine and thiamine pyrophosphate levels may confirm the diagnosis of deficiency.

Levels of thiamine in the blood are not reliable indicators of thiamine status. Low erythrocyte transketolase activity is also helpful.[32],[33] Transketolase concentrations of <120 nmol/L have also been used to indicate deficiency, while concentrations of 120â150 nmol/L suggest marginal thiamine status.[1] However, these tests are not routinely performed as it is time consuming, expensive, and may not be readily available.[34] The ETKA assay is a functional test rather than a direct measurement of thiamin status and therefore may be influenced by factors other than thiamine deficiency such as diabetes mellitus and polyneuritis.[1] Hence, treatment should be initiated in the absence of laboratory confirmation of thiamine deficiency. Furthermore, treatment should not be delayed if tests are ordered, but the results are awaited. Electroencephalographic abnormalities in thiamine deficiency states range from diffuse mild-to-moderate slow waves and are not a good diagnostic option, as the prevalence of abnormalities among patients is inconsistent.[35]Surrogate markers, which reflect chronic alcohol use and nutritional deficiency other than thiamine, may be helpful in identifying at-risk patients.

Therefore, the maximum amount of thiamine absorbed from 10 mg or higher dose is between 4.3 and 5.6 mg.[37] However, it has been suggested that, although thiamine transport occurs through the energy-requiring, sodium-dependent active process at physiologic concentrations, at higher supraphysiologic concentrations thiamine uptake is mostly a passive process.[38] Smithline et al. Have demonstrated that it is possible to achieve higher serum thiamine levels with oral doses up to 1500 mg.[39]In chronic alcohol users, intestinal absorption is impaired. Hence, absorption rates are expected to be much lower. It is approximately 30% of that seen in healthy individuals, i.e., 1.5 mg of thiamine is absorbed from 10 mg oral thiamine.[3] In those consuming alcohol and have poor nutrition, not more than 0.8 mg of thiamine is absorbed.[2],[3],[6] The daily thiamine requirement is 1â1.6 mg/day, which may be more in alcohol-dependent patients at risk for Wernicke encephalopathy.[1] It is highly likely that oral supplementation with thiamine will be inadequate in alcohol-dependent individuals who continue to drink.

Therefore, parenteral thiamine is preferred for supplementation in deficiency states associated with chronic alcohol use. Therapy involving parenteral thiamine is considered safe except for occasional circumstances of allergic reactions involving pruritus and local irritation.There is a small, but definite risk of anaphylaxis with parenteral thiamine, specifically with intravenous administration (1/250,000 intravenous injections).[40] Diluting thiamine in 50â100 mg normal saline for infusion may reduce the risk. However, parenteral thiamine should always be administered under observation with the necessary facilities for resuscitation.A further important issue involves the timing of administration of thiamine relative to the course of alcohol abuse or dependence. Administration of thiamine treatment to patients experiencing alcohol withdrawal may also be influenced by other factors such as magnesium depletion, N-methyl-D-aspartate (NMDA) receptor upregulation, or liver impairment, all of which may alter thiamine metabolism and utilization.[6],[14]Thiamine or other preparations (e.g., benfotiamine)The thiamine transporters limit the rate of absorption of orally administered thiamine.

Allithiamines (e.g., benfotiamine) are the lipid-soluble thiamine derivatives that are absorbed better, result in higher thiamine levels, and are retained longer in the body.[41] The thiamine levels with orally administered benfotiamine are much higher than oral thiamine and almost equals to intravenous thiamine given at the same dosage.[42]Benfotiamine has other beneficial effects including inhibition of production of advanced glycation end products, thus protecting against diabetic vascular complications.[41] It also modulates nuclear transcription factor ÎºB (NK-ÎºB), vascular endothelial growth factor receptor 2, glycogen synthase kinase 3 Î², etc., that play a role in cell repair and survival.[41] Benfotiamine has been found to be effective for the treatment of alcoholic peripheral neuropathy.[27]Dosing of thiamineAs the prevalence of thiamine deficiency is very common in chronic alcohol users, the requirement of thiamine increases in active drinkers and it is difficult to rapidly determine thiamine levels using laboratory tests, it is prudent that all patients irrespective of nutritional status should be administered parenteral thiamine. The dose should be 100 mg thiamine daily for 3â5 days during inpatient treatment. Commonly, multivitamin injections are added to intravenous infusions. Patients at risk for thiamine deficiency should receive 250 mg of thiamine daily intramuscularly for 3â5 days, followed by oral thiamine 100 mg daily.[6]Thiamine plasma levels reduce to 20% of peak value after approximately 2 h of parenteral administration, thus reducing the effective âwindow periodâ for passive diffusion to the central nervous system.[6] Therefore, in thiamine deficient individuals with features of Wernicke encephalopathy should receive thiamine thrice daily.High-dose parenteral thiamine administered thrice daily has been advocated in patients at risk for Wernicke encephalopathy.[43] The Royal College of Physicians guideline recommends that patients with suspected Wernicke encephalopathy should receive 500 mg thiamine diluted in 50â100 ml of normal saline infusion over 30 min three times daily for 2â3 days and sometimes for longer periods.[13] If there are persistent symptoms such as confusion, cerebellar symptoms, or memory impairment, this regimen can be continued until the symptoms improve.

If symptoms improve, oral thiamine 100 mg thrice daily can be continued for prolonged periods.[6],[40] A similar treatment regimen is advocated for alcoholic cerebellar degeneration as well. Doses more than 500 mg intramuscular or intravenous three times a day for 3â5 days, followed by 250 mg once daily for a further 3â5 days is also recommended by some guidelines (e.g., British Association for Psychopharmacology).[44]Other effects of thiamineThere are some data to suggest that thiamine deficiency can modulate alcohol consumption and may result in pathological drinking. Benfotiamine 600 mg/day as compared to placebo for 6 months was well tolerated and found to decrease psychiatric distress in males and reduce alcohol consumption in females with severe alcohol dependence.[45],[46] Other Factors During Thiamine Therapy Correction of hypomagnesemiaMagnesium is a cofactor for many thiamine-dependent enzymes in carbohydrate metabolism. Patients may fail to respond to thiamine supplementation in the presence of hypomagnesemia.[47] Magnesium deficiency is common in chronic alcohol users and is seen in 30% of individuals.[48],[49] It can occur because of increased renal excretion of magnesium, poor intake, decreased absorption because of Vitamin D deficiency, the formation of undissociated magnesium soaps with free fatty acids.[48],[49]The usual adult dose is 35â50 mmol of magnesium sulfate added to 1 L isotonic (saline) given over 12â24 h.[6] The dose has to be titrated against plasma magnesium levels.

Anaphylaxis has been reported at the rate of approximately 4/1 million pairs of ampoules of Pabrinex (a pair of high potency vitamins available in the UK containing 500 mg of thiamine (1:250,000 I/V administrations).[40] Intramuscular thiamine is reported to have a lower incidence of anaphylactic reactions than intravenous administration.[40] The reaction has been attributed to nonspecific histamine release.[51] Administer intravenous thiamine slowly, preferably by slow infusion in 100 ml normal saline over 15â30 min. Conclusions Risk factors for thiamine deficiency should be assessed in chronic alcohol users. A high index of suspicion and a lower threshold to diagnose thiamine deficiency states including Wernicke encephalopathy is needed. Several other presentations such as cerebellar syndrome, MBS, polyneuropathy, and delirium tremens could be related to thiamine deficiency and should be treated with protocols similar to Wernicke encephalopathy.

High-dose thiamine is recommended for the treatment of suspected Wernicke encephalopathy and related conditions [Figure 1]. However, evidence in terms of randomized controlled trials is lacking, and the recommendations are based on small studies and anecdotal reports. Nevertheless, as all these conditions respond to thiamine supplementation, it is possible that these have overlapping pathophysiology and are better considered as Wernicke encephalopathy spectrum disorders.Figure 1.

Indian J Psychiatry 2021;63:119-20The National Commission for Allied and Healthcare Professions Act, 2020 has been notified on March 28, 2021, by the Gazette of India published by the Ministry of levitra discount prices Law and Justice. This bill aims to âprovide for regulation and maintenance of standards of education and services by allied and healthcare professionals, assessment of institutions, maintenance of a Central Register and State Register and creation of a system to improve access, research and development and adoption of latest scientific advancement and for matters connected therewith or incidental thereto.â[1]This act has created a category of Health Care Professionals which is defined as. Âhealthcare professionalâ includes a scientist, therapist, or other professional who studies, advises, researches, supervises or provides preventive, curative, rehabilitative, levitra discount prices therapeutic or promotional health services and who has obtained any qualification of degree under this Act, the duration of which shall not be <3600 h spread over a period of 3 years to 6 years divided into specific semesters.[1]According to the act, âAllied health professionalâ includes an associate, technician, or technologist who is trained to perform any technical and practical task to support diagnosis and treatment of illness, disease, injury or impairment, and to support implementation of any healthcare treatment and referral plan recommended by a medical, nursing, or any other healthcare professional, and who has obtained any qualification of diploma or degree under this Act, the duration of which shall not be less than 2000 h spread over a period of 2 years to 4 years divided into specific semesters.â[1]It is noticeable that while the term âHealth Care Professionalsâ does not include doctors who are registered under National Medical Council, Mental Health Care Act (MHCA), 2017 includes psychiatrists under the ambit of Mental Health Care Professionals.[2] This discrepancy needs to be corrected - psychiasts, being another group of medical specialists, should be kept out of the broad umbrella of âMental Healthcare Professionals.âThe category of Behavioural Health Sciences Professional has been included and defined as âa person who undertakes scientific study of the emotions, behaviours and biology relating to a person's mental well-being, their ability to function in everyday life and their concept of self.

ÂBehavioural healthâ is the preferred term to âmental healthâ and includes professionals such as counselors, analysts, psychologists, educators and support workers, who provide counseling, therapy, and mediation services to individuals, families, groups, and communities in response to social and personal difficulties.â[1]This is a welcome step to the extent that it creates a diverse category of trained workforce in the field of Mental Health (Behavioural Health Science Professionals) and tries to regulate their training although it mainly aims to promote mental wellbeing. However there is a huge lacuna in levitra discount prices the term of âMental Illnessâ as defined by MHCA, 2017. Only severe disorders are included as per definition and there is no clarity regarding inclusion of other psychiatric disorders, namely âcommon mental disordersâ such as anxiety and depression. This leaves a strong possibility of concept of âpsychiatric illnessesâ being limited to only âsevere psychiatric disordersâ (major psychoses) thus perpetuating the stigma and alienation associated with psychiatric patients for levitra discount prices centuries. Psychiatrists being restricted to treating severe mental disorders as per MHCA, 2017, there is a strong possibility that the care of common mental disorders may gradually pass on under the care of âbehavioural health professionalsâ as per the new act!.

There is need to look into this aspect by the leadership in psychiatry, both organizational and academic psychiatry, and reduce the contradictions levitra discount prices between the MHCA, 2017 and this nascent act. All disorders classified in ICD 10 and DSM 5 should be classified as âPsychiatric Disordersâ or âMental Illness.â This will not only help in fighting the stigma associated with psychiatric illnesses but also promote the integration of psychiatry with other specialties.

Chronic alcohol use is associated with deficiency of thiamine along with other vitamins through several mechanisms.

Several neuropsychiatric syndromes have been associated with thiamine deficiency in the context of alcohol use disorder including WernickeâKorsakoff syndrome, alcoholic cerebellar levitra discount prices syndrome, alcoholic peripheral neuropathy, and possibly, MarchiafavaâBignami syndrome. High-dose thiamine replacement is suggested for these neuropsychiatric syndromes.Keywords.

High-dose thiamine strategy in WernickeâKorsakoff syndrome and related thiamine deficiency conditions associated with alcohol use disorder. Indian J levitra discount prices Psychiatry [serial online] 2021 [cited 2021 May 31];63:121-6. Available from. Https://www.indianjpsychiatry.org/text.asp?. 2021/63/2/121/313716 Introduction Thiamine is a water-soluble vitamin (B1) that plays a key role in the activity of several enzymes associated with energy metabolism.

Thiamine pyrophosphate (or diphosphate) is the active form that acts as a cofactor for enzymes. The daily dietary requirement of thiamine in adults is 1â2 mg and is dependent on carbohydrate intake.[1],[2] The requirement increases if basal metabolic rate is higher, for example, during alcohol withdrawal state. Dietary sources include pork (being the major source), meat, legume, vegetables, and enriched foods. The body can store between 30 and 50 mg of thiamine and is likely to get depleted within 4â6 weeks if the diet is deficient.[2] In those with alcohol-related liver damage, the ability to store thiamine is gradually reduced.[1],[2]Lower thiamine levels are found in 30%â80% of chronic alcohol users.[3] Thiamine deficiency occurs due to poor intake of vitamin-rich foods, impaired intestinal absorption, decreased storage capacity of liver, damage to the renal epithelial cells due to alcohol, leading to increased loss from the kidneys, and excessive loss associated with medical conditions.[2],[3] Furthermore, alcohol decreases the absorption of colonic bacterial thiamine, reduces the enzymatic activity of thiamine pyrophosphokinase, and thereby, reducing the amount of available thiamine pyrophosphate.[4] Since facilitated diffusion of thiamine into cells is dependent on a concentration gradient, reduced thiamine pyrophosphokinase activity further reduces thiamine uptake into cells.[4] Impaired utilization of thiamine is seen in certain conditions (e.g., hypomagnesemia) which are common in alcohol use disorder.[2],[3],[4] This narrative review discusses the neuropsychiatric syndromes associated with thiamine deficiency in the context of alcohol use disorder, and the treatment regimens advocated for these conditions. A PubMed search supplemented with manual search was used to identify neuropsychiatric syndromes related to thiamine deficiency in alcohol use disorder patients.

The treatment suggestions in the guidelines vary widely. Furthermore, hardly any evidence-based recommendations exist on a more general use of thiamine as a preventative intervention in individuals with alcohol use disorder.[13] There are very few studies that have evaluated the dose and duration of thiamine for WKS, but higher doses may result in a greater response.[6],[14] With thiamine administration rapid improvement is seen in eye movement abnormalities (improve within days or weeks) and ataxia (may take months to recover), but the effects on memory, in particular, are unclear.[4],[14] Severe memory impairment is the core feature of Korsakoff syndrome. Initial stages of the disease can present with confabulation, executive dysfunction, flattened affect, apathy, and poor insight.[15] Both the episodic and semantic memory are affected, whereas, procedural memory remains intact.[15]Thomson et al.[6] suggested the following should be treated with thiamine as they are at high risk for developing WKS. (1) all patients with any evidence of chronic alcohol misuse and any of the following. Acute confusion, decreased conscious level, ataxia, ophthalmoplegia, memory disturbance, and hypothermia with hypotension.

(2) patients with delirium tremens may often also have Wernicke encephalopathy, therefore, all of these patients should be presumed to have Wernicke encephalopathy and treated, preferably as inpatients. And (3) all hypoglycemic patients (who are treated with intravenous glucose) with evidence of chronic alcohol ingestion must be given intravenous thiamine immediately because of the risk of acutely precipitating Wernicke encephalopathy.Alcoholic cerebellar syndromeChronic alcohol use is associated with the degeneration of anterior superior vermis, leading to a clinical syndrome characterized by the subacute or chronic onset of gait ataxia and incoordination in legs, with relative sparing of upper limbs, speech, and oculomotor movements.[16] In severe cases, truncal ataxia, mild dysarthria, and incoordination of the upper limb is also found along with gait ataxia. Thiamine deficiency is considered to be the etiological factor,[17],[18] although direct toxic effects of alcohol may also contribute to this syndrome. One-third of patients with chronic use of alcohol have evidence of alcoholic cerebellar degeneration. However, population-based studies estimate prevalence to be 14.6%.[19] The effect of alcohol on the cerebellum is graded with the most severe deficits occurring in alcohol users with the longest duration and highest severity of use.

The diagnosis of cerebellar degeneration is largely clinical. MRI can be used to evaluate for vermian atrophy but is unnecessary.[20] Anterior portions of vermis are affected early, with involvement of posterior vermis and adjacent lateral hemispheres occurring late in the course could be used to differentiate alcoholic cerebellar degeneration from other conditions that cause more diffuse involvement.[21] The severity of cerebellar syndrome is more in the presence of WKS, thus could be related to thiamine deficiency.[22],[23] Therefore, this has been considered as a cerebellar presentation of WKS and should be treated in a similar way.[16] There are anecdotal evidence to suggest improvement in cerebellar syndrome with high-dose thiamine.[24]Alcoholic peripheral neuropathyPeripheral neuropathy is common in alcohol use disorder and is seen in 44% of the users.[25] It has been associated predominantly with thiamine deficiency. However, deficiency of other B vitamins (pyridoxine and cobalamin) and direct toxic effect of alcohol is also implicated.[26] Clinically, onset of symptoms is gradual with the involvement of both sensory and motor fibers and occasionally autonomic fibers. Neuropathy can affect both small and large peripheral nerve fibers, leading to different clinical manifestations. Thiamine deficiency-related neuropathy affects larger fiber types, which results in motor deficits and sensory ataxia.

Most advanced findings include weakness and muscle atrophy.[20] Progression is very gradual over months and involvement of upper limbs may occur late in the course. Diagnosis begins with laboratory evaluation to exclude other causes of distal, sensorimotor neuropathy including hemoglobin A1c, liver function tests, and complete blood count to evaluate for red blood cell macrocytosis. Cerebrospinal fluid studies may show increased protein levels but should otherwise be normal in cases of alcohol neuropathy and are not recommended in routine evaluation. Electromyography and nerve conduction studies can be used to distinguish whether the neuropathy is axonal or demyelinating and whether it is motor, sensory, or mixed type. Alcoholic neuropathy shows reduced distal, sensory amplitudes, and to a lesser extent, reduced motor amplitudes on nerve conduction studies.[20] Abstinence and vitamin supplementation including thiamine are the treatments advocated for this condition.[25] In mild-to-moderate cases, near-complete improvement can be achieved.[20] Randomized controlled trials have showed a significant improvement in alcoholic polyneuropathy with thiamine treatment.[27],[28]MarchiafavaâBignami syndromeThis is a rare but fatal condition seen in chronic alcohol users that is characterized by progressive demyelination and necrosis of the corpus callosum.

The association of this syndrome with thiamine deficiency is not very clear, and direct toxic effects of alcohol are also suggested.[29] The clinical syndrome is variable and presentation can be acute, subacute, or chronic. In acute forms, it is predominantly characterized by the altered mental state such as delirium, stupor, or coma.[30] Other clinical features in neuroimaging confirmed MarchiafavaâBignami syndrome (MBS) cases include impaired gait, dysarthria, mutism, signs of split-brain syndrome, pyramidal tract signs, primitive reflexes, rigidity, incontinence, gaze palsy, diplopia, and sensory symptoms.[30] Neuropsychiatric manifestations are common and include psychotic symptoms, depression, apathy, aggressive behavior, and sometimes dementia.[29] MRI scan shows lesions of the corpus callosum, particularly splenium. Treatment for this condition is mostly supportive and use of nutritional supplements and steroids. However, there are several reports of improvement of this syndrome with thiamine at variable doses including reports of beneficial effects with high-dose strategy.[29],[30],[31] Early initiation of thiamine, preferably within 2 weeks of the onset of symptoms is associated with a better outcome. Therefore, high-dose thiamine should be administered to all suspected cases of MBS.

Laboratory Diagnosis of Thiamine Deficiency Estimation of thiamine and thiamine pyrophosphate levels may confirm the diagnosis of deficiency. Levels of thiamine in the blood are not reliable indicators of thiamine status. Low erythrocyte transketolase activity is also helpful.[32],[33] Transketolase concentrations of <120 nmol/L have also been used to indicate deficiency, while concentrations of 120â150 nmol/L suggest marginal thiamine status.[1] However, these tests are not routinely performed as it is time consuming, expensive, and may not be readily available.[34] The ETKA assay is a functional test rather than a direct measurement of thiamin status and therefore may be influenced by factors other than thiamine deficiency such as diabetes mellitus and polyneuritis.[1] Hence, treatment should be initiated in the absence of laboratory confirmation of thiamine deficiency. Furthermore, treatment should not be delayed if tests are ordered, but the results are awaited. Electroencephalographic abnormalities in thiamine deficiency states range from diffuse mild-to-moderate slow waves and are not a good diagnostic option, as the prevalence of abnormalities among patients is inconsistent.[35]Surrogate markers, which reflect chronic alcohol use and nutritional deficiency other than thiamine, may be helpful in identifying at-risk patients.

This includes gamma glutamate transferase, aspartate aminotransferase. Alanine transaminase ratio >2:1, and increased mean corpuscular volume.[36] They are useful when a reliable history of alcohol use is not readily available, specifically in emergency departments when treatment needs to be started immediately to avoid long-term consequences. Thiamine Replacement Therapy Oral versus parenteral thiamineIntestinal absorption of thiamine depends on active transport through thiamine transporter 1 and 2, which follow saturation kinetics.[1] Therefore, the rate and amount of absorption of thiamine in healthy individuals is limited. In healthy volunteers, a 10 mg dose results in maximal absorption of thiamine, and any doses higher than this do not increase thiamine levels. Therefore, the maximum amount of thiamine absorbed from 10 mg or higher dose is between 4.3 and 5.6 mg.[37] However, it has been suggested that, although thiamine transport occurs through the energy-requiring, sodium-dependent active process at physiologic concentrations, at higher supraphysiologic concentrations thiamine uptake is mostly a passive process.[38] Smithline et al.

Have demonstrated that it is possible to achieve higher serum thiamine levels with oral doses up to 1500 mg.[39]In chronic alcohol users, intestinal absorption is impaired. Hence, absorption rates are expected to be much lower. It is approximately 30% of that seen in healthy individuals, i.e., 1.5 mg of thiamine is absorbed from 10 mg oral thiamine.[3] In those consuming alcohol and have poor nutrition, not more than 0.8 mg of thiamine is absorbed.[2],[3],[6] The daily thiamine requirement is 1â1.6 mg/day, which may be more in alcohol-dependent patients at risk for Wernicke encephalopathy.[1] It is highly likely that oral supplementation with thiamine will be inadequate in alcohol-dependent individuals who continue to drink. Therefore, parenteral thiamine is preferred for supplementation in deficiency states associated with chronic alcohol use. Therapy involving parenteral thiamine is considered safe except for occasional circumstances of allergic reactions involving pruritus and local irritation.There is a small, but definite risk of anaphylaxis with parenteral thiamine, specifically with intravenous administration (1/250,000 intravenous injections).[40] Diluting thiamine in 50â100 mg normal saline for infusion may reduce the risk.

However, parenteral thiamine should always be administered under observation with the necessary facilities for resuscitation.A further important issue involves the timing of administration of thiamine relative to the course of alcohol abuse or dependence. Administration of thiamine treatment to patients experiencing alcohol withdrawal may also be influenced by other factors such as magnesium depletion, N-methyl-D-aspartate (NMDA) receptor upregulation, or liver impairment, all of which may alter thiamine metabolism and utilization.[6],[14]Thiamine or other preparations (e.g., benfotiamine)The thiamine transporters limit the rate of absorption of orally administered thiamine. Allithiamines (e.g., benfotiamine) are the lipid-soluble thiamine derivatives that are absorbed better, result in higher thiamine levels, and are retained longer in the body.[41] The thiamine levels with orally administered benfotiamine are much higher than oral thiamine and almost equals to intravenous thiamine given at the same dosage.[42]Benfotiamine has other beneficial effects including inhibition of production of advanced glycation end products, thus protecting against diabetic vascular complications.[41] It also modulates nuclear transcription factor ÎºB (NK-ÎºB), vascular endothelial growth factor receptor 2, glycogen synthase kinase 3 Î², etc., that play a role in cell repair and survival.[41] Benfotiamine has been found to be effective for the treatment of alcoholic peripheral neuropathy.[27]Dosing of thiamineAs the prevalence of thiamine deficiency is very common in chronic alcohol users, the requirement of thiamine increases in active drinkers and it is difficult to rapidly determine thiamine levels using laboratory tests, it is prudent that all patients irrespective of nutritional status should be administered parenteral thiamine. The dose should be 100 mg thiamine daily for 3â5 days during inpatient treatment. Commonly, multivitamin injections are added to intravenous infusions.

Patients at risk for thiamine deficiency should receive 250 mg of thiamine daily intramuscularly for 3â5 days, followed by oral thiamine 100 mg daily.[6]Thiamine plasma levels reduce to 20% of peak value after approximately 2 h of parenteral administration, thus reducing the effective âwindow periodâ for passive diffusion to the central nervous system.[6] Therefore, in thiamine deficient individuals with features of Wernicke encephalopathy should receive thiamine thrice daily.High-dose parenteral thiamine administered thrice daily has been advocated in patients at risk for Wernicke encephalopathy.[43] The Royal College of Physicians guideline recommends that patients with suspected Wernicke encephalopathy should receive 500 mg thiamine diluted in 50â100 ml of normal saline infusion over 30 min three times daily for 2â3 days and sometimes for longer periods.[13] If there are persistent symptoms such as confusion, cerebellar symptoms, or memory impairment, this regimen can be continued until the symptoms improve. If symptoms improve, oral thiamine 100 mg thrice daily can be continued for prolonged periods.[6],[40] A similar treatment regimen is advocated for alcoholic cerebellar degeneration as well. Doses more than 500 mg intramuscular or intravenous three times a day for 3â5 days, followed by 250 mg once daily for a further 3â5 days is also recommended by some guidelines (e.g., British Association for Psychopharmacology).[44]Other effects of thiamineThere are some data to suggest that thiamine deficiency can modulate alcohol consumption and may result in pathological drinking. Benfotiamine 600 mg/day as compared to placebo for 6 months was well tolerated and found to decrease psychiatric distress in males and reduce alcohol consumption in females with severe alcohol dependence.[45],[46] Other Factors During Thiamine Therapy Correction of hypomagnesemiaMagnesium is a cofactor for many thiamine-dependent enzymes in carbohydrate metabolism. Patients may fail to respond to thiamine supplementation in the presence of hypomagnesemia.[47] Magnesium deficiency is common in chronic alcohol users and is seen in 30% of individuals.[48],[49] It can occur because of increased renal excretion of magnesium, poor intake, decreased absorption because of Vitamin D deficiency, the formation of undissociated magnesium soaps with free fatty acids.[48],[49]The usual adult dose is 35â50 mmol of magnesium sulfate added to 1 L isotonic (saline) given over 12â24 h.[6] The dose has to be titrated against plasma magnesium levels.

It is recommended to reduce the dose in renal failure. Contraindications include patients with documented hypersensitivity and those with heart block, Addison's disease, myocardial damage, severe hepatitis, or hypophosphatemia. Do not administer intravenous magnesium unless hypomagnesemia is confirmed.[6]Other B-complex vitaminsMost patients with deficiency of thiamine will also have reduced levels of other B vitamins including niacin, pyridoxine, and cobalamin that require replenishment. For patients admitted to the intensive care unit with symptoms that may mimic or mask Wernicke encephalopathy, based on the published literature, routine supplementation during the 1st day of admission includes 200â500 mg intravenous thiamine every 8 h, 64 mg/kg magnesium sulfate (â4â5 g for most adult patients), and 400â1000 Î¼g intravenous folate.[50] If alcoholic ketoacidosis is suspected, dextrose-containing fluids are recommended over normal saline.[50] Precautions to be Taken When Administering Parenteral Thiamine It is recommended to monitor for anaphylaxis and has appropriate facilities for resuscitation and for treating anaphylaxis readily available including adrenaline and corticosteroids. Anaphylaxis has been reported at the rate of approximately 4/1 million pairs of ampoules of Pabrinex (a pair of high potency vitamins available in the UK containing 500 mg of thiamine (1:250,000 I/V administrations).[40] Intramuscular thiamine is reported to have a lower incidence of anaphylactic reactions than intravenous administration.[40] The reaction has been attributed to nonspecific histamine release.[51] Administer intravenous thiamine slowly, preferably by slow infusion in 100 ml normal saline over 15â30 min.

Conclusions Risk factors for thiamine deficiency should be assessed in chronic alcohol users. A high index of suspicion and a lower threshold to diagnose thiamine deficiency states including Wernicke encephalopathy is needed. Several other presentations such as cerebellar syndrome, MBS, polyneuropathy, and delirium tremens could be related to thiamine deficiency and should be treated with protocols similar to Wernicke encephalopathy. High-dose thiamine is recommended for the treatment of suspected Wernicke encephalopathy and related conditions [Figure 1]. However, evidence in terms of randomized controlled trials is lacking, and the recommendations are based on small studies and anecdotal reports.

Nevertheless, as all these conditions respond to thiamine supplementation, it is possible that these have overlapping pathophysiology and are better considered as Wernicke encephalopathy spectrum disorders.Figure 1.
